PHOTOGRAPHIC-PRINTING FRAME.

Application filed September 4, 1909.

Specification of Letters Patent.

T0 aU 'whom t may concern Be it known that I, FRANCIS LEE PIERRES- norr,a citizen of the United States, and resident of the borough ofManhattan, city, county, and State of New York, have invented certainnew and useful Improvements in Photographic-Printing Frames, of whichthe following is a specification.

My invention relates to frames for holding the negative and paper duringthe printing of photographs and has for its object to provide suchframes with a simple and easily operated locking device, which may alsobe used as a handle for handling said frame.

My invention will be fully described hereinafter and the features ofnovelty will be pointed out in the appended claim.

Reference is to be had to the accompanying drawings in which- Figure 1is a face view of my improved frame; Fig. 2 is a sectional view thereofon the line 2 2 of Fig. 1; and Fig. 3 is a section of the removable backtaken on the line 3-3 of Fig. 1.

In the drawing, 1 represents the frame proper, which may be made ofmetal, wood, or any other suitable material and is provided. with thecustomary 'annular liange 2 arranged to support the glass 3.

4 represents the removable back prefer'- ably provided on its onesurface with a facing of felt or similar material 5 and arranged toengage the negative and the paper to hold same in position in the framein the usual manner.

6 is a handle rotatablyV mounted in a bushing 7 secured to the back 4and provided with oppositely extending lugs 8. Latches 9 are pivotallysecured at 10 to each of said lugs 8 and extend in opposite directionsthrough guides 11 secured to the back 4 at proper points. The ends ofthe latches 9 are turned upwardly and back as indicated at 12 and arearranged to enter recesses 13 formed in the frame 1. It is to beunderstood that the portions 12 of the latches 9 form resilient meansadapted to engage the upper walls of the recesses 13.

In operation, when it is desired to use the frame for printing purposesthe handle 6 is rotated and with it the lugs S, so as to withdraw thelatches 9 from the recesses 13. The back 4 may now be easily removed bymeans of the handle G so as to permit the negative and the paper to bereadily placed in position in the frame. After this has been done theback 4 is returned to position and the handle 6 rotated in the oppositedirection to return the end portions 12 of the latches 9 into therecesses 13. It will thus be seen that with my improved locking means anentire releasing and locking operation may be performed with one handonly, leaving the other hand free to hold the frame or to manipulate thenegative and paper, as may be found necessary.

Heretofore, it has been found compulsory, in order to secure asatisfactory result, to usc both hands in the releasing and re-lockingof the back. The handle G of my improved construction, as will bereadily seen, may be used as a convenient means for handling the frameand may also be used as a support for supporting the frame in aninclined position during the printing.

It is to be distinctly understood that I do not limit myself to the useof two latches 9 as more or less may be used if found convenient.Various modifications may be made without departing from the spirit ofmy invention, as defined in the claim.

I claim as my invention:

In a device of the kind described, a rectangular frame provided withoppositely located recesses, a glass plate supported in said frame, arigid rectangular back fitted within said frame with its inner surfacein engagement with said plate and provided with a socket having areduced portion, said back being bodily removable from said frame, ahandle rotatably mounted in said socket and arranged to manipulate saidback as a unit, a removable washer of larger diameter than the reducedportion of said socket secured to said handle whereby removal of saidhandle from said socket is prevented, projections carried bv said handleto rotate therewith and extending in opposite directions therefrom,normally alining slides mounted on the outer surface of said back so asto be guided by said outer surface and having their inner ends pivoteddirect-ly to said projections, said slides having their outer ends bentupon themselves to form resilient latches arranged to be moved into andout of said recesses as the handle 1s rotated whereby the back s pressedagainst my hand n the presence of two subscribing said plate or releasedfor removal from said witnesses.

frame and guides secured to said back for FRANCIS LEE HERRESHOFFmaintaining Said slides n engagement with the outer surface thereof andfor preventing Vtnesses:

any substantial lateral movement thereof. JOHN A. KEHLENBECK,

In testlmony whereof I have hereunto set FRED A. KLEIN.
